tween the cover 3 and outer surface of the mouth of the bottle or receptacle,

The cap is formed in practice of a single piece of sheet-metal, cut out and stamped up through the action of a suitable die in a single operation, or in two or more successive operations, as desired. In the application of the cap to the bottle, the cap is fitted in the usual manner upon the up er end of the bottle neck so as to coniine tlie scaling disk yin position, after which the lower edge of the flange 4, which is of sufficient depth to extend below the base of the' yshoulder 2, is crimpedl under and into engagement lwith said shoulder, as

tion.

The flange 4 has a portion 7, constituting practically one -half of the entire circumferenti'al length o f the flange, intact with which constitutes the other half thereof?, partially separated 'from the top or cover and adaptedv to be displaced out of normal j position vand separated' from the top or cover in the operation of removing the cap,

As shown, the body portion 3 vof the top is provided with a segmental slit,9, disposed ,l some distance inwardly from the upper-edge j of the flange portion 8, said slit extending radially outward at one end to the edge of the flange, as at 10, and terminating at its opposite end inwardly from the edge of the lflange, as at l1, this construction separating the flange portion' 8 from the body' of the ltop except at the end adjacent the slit-ter- `minal 11, as hereinafter described, and providing the same with an inwardly projecting segmental lip 12 lapping over upon the adjacent portion of theV scalino' disk 5.

In order to close the slit, as well 'as to adaptl the cover to exert uniform pressure at all points upon the sealing disk 5, the edge v9? crown formed by producing the slit and which is primarily concentric with the center of the top, is drawn out to extend on a line eccentric to the c enter of the top so that it will extend under the edgey of the lip 12 and be overlapped thereby, While the Alip l2 is provided with one or more offset portions or projections 13 to lap some little distan-:se overupon the edge of the top, thus lventing the free edge of the top from s; g i ing up from fcntact with the seal and neinat 6, thus fastening the cap in applied posithe top or cover portion 3, and a portion 8,

the slit and prevent spreading of the material along. the line of of the top or In the production of this boss,

.u on lthe lip vThese -o`set however, be

tainingthe parts along the line of the joint ysubstantially flush, so that thev pressure upon the seal will be uniform or substan tially so over the entire varea thereof.

It is to be understood that the top, crown or cover portion 3 of the cap is primarily of a true ,circular form, and that the slit 9 is cut on-a true segmental line concentric with 'the center` of such top, after which the .free

, the free edge of the vtop'may be conveniently effected through the action of the die by which the cap v41s stamped up from the blank, by constructing the die-so as to outwardly offset the free portion of the top in the form of a segmental boss extending around said free edge, and then during the second operation of scoring the cap to produce the 'weakened line simultaneously flattening out the embossed portion of the c a'p. the lmetal of the free portion ofthe top is simply stretched or expanded, and is foreshortened only to an extent to slightly space theI edge of suchl portion from the'edge of the flange 12, so

thatupon the subsequent operation of flattening out the boss the free portion of the top4 will be expanded under the flange to form the lap joint.

- It will be understood that after the boss is formed and prior to the operation of flattemng out the same the offset portions or projections 13 maybe conveniently formed 12 by the action of a suitable affecting the top of the cap.

ortions or plrojections may,

ispensed wit sion of the -free edge' of the top beneath the lip 12 Will forma sufficiently close joint under die without 'all ordinary conditions.

The end of the flange portion 8 adjacent tothe terminal 10 of the'slit is unreduced and unweakened and is integral with the contiguous portion of the flange section 7, while the' other end of the flange portionI 8 is con-v nected with ,the top and intact flange portion in such manner as'to be readily severed therefrom. This is accomplished by scoring,

grooving, Aindenting or otherwise weakening the metal along the diagonal line 14'extending continuously upward from the. lower ledge of the flange overupon the top ofthe cap to the terminal 1,1 of the slit, forming an intact portion which joins thefdisplaceable as the exten? portion of the flange but is sufficiently weak-A ened to 'Lpermit-v breaking lor tearing. of thi` metal alongsaidl-iiieto free the' adjacent end of the displaceable" flange lportion for sepa" ration except'at its intact 'end from the body of the cap. ln order to enable the parts to be torn or separated and the displaceable portion 8 to be moved away from the bodyy of the ca a linger or tearing tab 15 is, provided,v w iich is integral with the lower end of the flange portion 8 and in the application of the cap is bent inward `to lie'beneath the shoulder 2 so as to occupy a non-interfering position. By straightening this tab by an 4upward and outward pull, and continuing such pull'in an. upward and forward direction,

the metal may be torn oi broken along the line 14' to separate the portions up to the line of the slit terminal 11, thus breaking the adjacent end of the flange portion 8 away from the bodyof the cap and permitting said portion to beswung outward on its opposite or intact end as a fulcruni, as indicated in Fig. 3; so that the body of the cap may be slipped transversely 0H' the -jar and disengaged with the flange 2 thereof.

i lt will 'thus be seen that a cap is provided in which all ofitspoitions 'are formed 'of a single piece of material and are normally in condition for use, requiring n'o contract-ion,

`in :a circumferential way, of theflange or other manipulation of ,the iarts, other than the bending of the lower e ge of the cap under the shoulder Zito apply 'said' cap tothe bottle, or jar. Hence, the operation of ap- ,plying the capis simplifiedover constructionslof that kind in whiclitlie displaceable portion of the-flange' is entirely separated from the-top of the cap and expanded for the v application'of the cap and drawn into normalv position'by the contraction of a connecting web, and furthermore, a cap of .superioris produced. After the cap has I strength been initially removed to unseal thevcontainer, it may be subsequently used as a cover by restoring the disp aceable portion to normal' positionfin whic while it will no longer be permanentl connected atl its free end with the body o "the cap., the cap will neverthelessbe capable inv connection with the sealing disk of closing the receptacle in a sufficiently tight manner.

l In the modified` forin-y of the invention shown in' Figs. 4 and 5 the construction is substantially the saine as that hereinbefore disclosed, except'that the cap is provided vwith a pair of upwardly converging weakening lines 14.i
